Rainbow Energy

Rainbow Energy is sitting still at £2.49 while the set has climbed 16.2% over the last month — a warning sign on a card that's been flat for 35 days. The real puzzle is the gap between UK asks and Cardmarket: sellers here are asking only 28% of the continental trend, with nine copies listed from £2.40 up, though the cheapest one is graded MP and a cleaner example would command more. Worth noting that this holo version trades at 14.8 times the plain printing (£8.60 against £0.58), so you're buying the art and finish, not the function.
